Floyd Mayweather wants his megafight with Conor McGregor to 'cost Irish fans over €100 on pay-per-view', according to boxing promoter Eddie Hearn.

The Las Vegas bout is less than four weeks away but fight fans in Ireland and the UK are still uncertain how much the fight will cost to view and on what channel it will be shown.

There has been reports from Los Angeles Times reporter Lance Pugmire that the fight could cost American fans as much as $99.99 and Hearn in an interview with GQ magazine revealed that Mayweather has a similar price range in mind for the Irish and UK market.

And the Irishman looks to have taken some of his MMA moves into the boxing ring.

The pictures show him towering over his floored opponent as veteran referee Joe Cortez races in to break up the session.

He brought Cortez in to ensure he knows the rules before facing Mayweather next month.

"What I'm doing with the sparring sessions, we try to do everything to simulate the real fight from the instructions at the beginning to everything that goes on in a real fight," the 73-year-old said.

“He has been doing very well. I was pretty impressed with everything he knows.

“We’re going to practice everything. If he scores a knockdown, he has to go to a neutral corner. He has to understand that there could be more than three knockdowns in a round, and teach him that there’s a mandatory eight count."
